* src/xdisp.c (note_mouse_highlight): Don't attempt to highlight tab-bar buttons. (note_tab_bar_highlight): Function deleted: it had no effect on display of tab-bar buttons. (tab_bar_item_info): Mention all arguments in the commentary. (get_tab_bar_item): Don't pay attention to mouse-highlight information; instead, compare the button's index with the one recorded in f->last_tab_bar_item. (handle_tab_bar_click): Don't attempt to show tab-bar buttons in pressed or released state: that isn't supported. Determine whether to generate a tab-bar button click based on DOWN_P argument, not on mouse-highlight, which has no effect on tab-bar display. (Bug#47581)
